What has changed so drastically in OA that the game requires hardware upgrades?

My Pc meets and exceeds the min and the recommended requirements for the games from OFP - Arma 2... Why is it that in OA the recommended hardware has changed so drastically from Arma 2?

My PC meets the min req for OA but does not meet the recommended req. However for Arma 2 it meets min and also the recommended req for Arma 2...

What gives BIS? What changes did you makes hardware wise that has raised the bar in OA?

extremely high detailed tree models. they figure since there's less trees in the desert, why not go crazy on the polygons.

That is your own assumption, which you cannot back up..

@Baz: that is most likely because of the new AO SSAO and maybe the new lighting system

i've noticed that the lighting is very different and everything looks alot sharper too.

Indoor environment with furniture?

But honestly if you can run Arma 2 okay you will probably run OA okay as well.

Try the demo if you are unsure...

well that assumption got a point. try to run chernarus map on combined ops. you will experience a lots of fps downs comparing to the vanilla arma 2.

The lighting is very much improved in OA

My guess is the ArmA II requirements weren't high enough, and they just changed them for the OA release, to something more accurate. I mean who has tried to run ArmA II on a 7800GT? According to CYRI, my Laptop(Acer Aspire 5251-1658) can run ArmA II, but I know from personal experience that it will not run, at least not smoothly.

EDIT: It's actually probably SSAO.

why doesn't can you run it detect the right gfx card in my rig? :P

The have done some engine improvements from arma2 to OA, and it might be a few of those that needs more power for the puters?

OA was alot harder to run for me, my 4870x2 struggled to run it at even lower settings than I ran ArmA 2 at, I ran A2 at Very High settings all maxed out, had to upgrade to a GTX 480 just to get 40 + FPS.

60 fps here yall can it

i dont know why oa runs a bit worse, but it's generally running better for me now , at least since the latest beta.

I think its the new SSAO added to the game which really makes it look alot nicer! :)

If only they could make the trees not look like blobs all the time...then I would be perfectly happy! :D

[ffur2007slx2_5 11]

maybe the trajectory caculation need more memory.

[mrcash2009 0]

Yes, its mainly to do with the buildings too, alot more poly's/pathfinding options/calculations with all the now enter-able huts and buildings.

try to run chernarus map on combined ops. you will experience a lots of fps downs comparing to the vanilla arma 2.

This is a good example though.

Agreed. :)

[Imperator[TFD] 444]

It's the SSAO, not the buildings, that is the culprit.

And the game looks phenomenal with it on.

And then there is AA. I have to use High(8xAA) with OA, as compared to "normal"(4xAA) forA2 because OA is a jaggie crappy mess, relative to Arma2.And even with 8XAA, there is STILL jaggies...

4870x2

- Post-processing is heavier and handled differently in OA. "Disable" it and you get the same as "low" in Arma 2 (ie : you still get some colour effects, but no blur etc...). Low is like normal in Arma 2, and with "normal" and up in OA you get SSAO to kick in, which is a killer for low-end cards.

- Much more interiors and partially destructible buildings : a lot of polygons.

- regarding 4870x2 struggling, that's probably a driver issue with no correct profile for OA to manage multi-gpu. Maybe try rename the exe to arma 2?

[enad 11]

I tried alot when I had the 4870x2, renaming it and stuff, They even released Crossfire Profiles, but that didn't really help at all. My GTX 480 is running it great though. :)
